Re: Deploying/Undeploying application using the manager webapp
Log4j solved an issue like this using the following entity resolver... http://cvs.apache.org/viewcvs.cgi/jakarta-log4j/src/java/org/apache/log4j/xml/Log4jEntityResolver.java Jake At 11:07 PM 6/2/2003 -0500, you wrote: We just chased down a problem with the struts jar file being locked after being removed by the manager.

Jacob, Thanks for the reply.

Re: Deploying/Undeploying application using the manager webapp
We just chased down a problem with the struts jar file being locked after being removed by the manager. The solution I found in the struts mailing list archives was to add the dtd files from the struts jar file to WEB-INF/classes as a work-around. Maybe that will get you pointed in the right direction on your locking problem. Good luck. Best Regards, Jason Koeninger JJ Computer Consulting http://www.jjcc.com Rais Bonny wrote: Thanks again.
